Shentai Peak Dazhai disappeared in one day, and a thousand villagers and three hundred traps demolished the Dazhai completely, and even the wood of the wall was resisted and used to build houses.

The old bustard of Cuixianglou and a few turtle women who are secretly smiling all day long, they have been annoying Lou for four or five days, just arrived here, the house has not been built, the business is so hot that all the hundred or so girls are tired, even the fox who has been stabbed a few times on the face is also busy with back pain, a few old bustards and turtle women almost rolled up their sleeves and went into battle in person.

Today, I don't know what kind of madness the group of Guan Dijun has, hundreds of people swarmed over, and the team lined up on the edge of the Xiaojian River, filling the pockets of a few old bustards and turtle women, so that they hurriedly sent people to Taiyuan to buy dozens of girls.

What they didn't know was that these relaxed Guan Di troops, under the command of Liu Youzhu and Li Dingliang, crossed the Fen River in groups of three or five, plunged headlong into the towering mountains, and then quietly went north along Yunzhong Mountain.

This time, Mengjiazhuang was almost exhausted, more than 500 elite Guan Emperor troops were temporarily transferred, half of them were fifty tigers and leopards composed of old bandits from Jiuji Mountain, the left and right generals were Liu Youzhu and Li Dingliang, the former army was exploring the way, and Lao Huang would lead the dozens of people in Lan County, keeping an eye on the grain transportation team and informing Qinchuan at any time.

Luo Da Niu knelt so much that his knees were broken, and he also shouted hoarsely, but Qin Chuan still left him behind.

Mengjiazhuang is the base camp of Qinchuan, there are 14,000 stone grain in the Zhuangzi, and there are more than 10,000 taels of silver, this place must not be lost.

Mengjiazhuang was garrisoned by Luo Ba's ten-fang battalion, with a strength of 300, Wang Jizong counsellor for defense, and transferred some villagers to temporarily strengthen the defense facilities outside the village, dig more trenches, and set up more horses.

Song Zhiting was in charge of the two mines of Montenegro and Hongli Mountain, transporting all the pig iron and coke from Hongli Mountain to Montenegro in advance, and the personnel were also ready to evacuate to Jingyou or Lou Fu at any time, while the Montenegro mine built a large number of defense facilities, and all miners had to spend an hour every day to practice defense.

Jingyou Town was garrisoned by the 300 Wudang Battalion, and after the battalion officer Liu Youzhu was transferred, Huang Liuxi, who had half of his face blown off by the bird's gun, was temporarily dispatched.

Luo Da Niu's first camp will continue to attack Ren Liang and Wang Gang and Leopard Wu, continue to weaken their strength, and they must be exterminated before the summer harvest next year, otherwise it will be very unsafe when harvesting grain.

In addition, Luo Daniu also has to assist in the defense of Mengjiazhuang, Jingyou Town and Montenegrin mines, and return to help at any time, the burden on his shoulders is the heaviest, and he also has the right to mobilize the garrisons of Jingyou and Montenegro.

In order to give him a chance to perform, Qin Chuan also gave him a task, to clear the spies who traveled to the east village of Lan County, and to attract the spies of the Zhang family and several other families in Lan County to the west, so that Liu Youzhu and Li Dingliang's people could reach Ningwu Pass unnoticed.

Luo Da Niu was a little depressed, led the men and horses, and when he saw those big spies, he killed them violently without saying a word, and others escaped faster than rabbits, and he chased after them like hunting dogs.

After a long toss, he killed more than a dozen spies, and this Jingyou went to the East Village of Lan County to make a miasma, and even went to the East Village to show off his might for a while.

The big families in Lan County have transferred all the spies over and kept an eye on his movements.

Especially the Zhang family, the Ma family and the Chen family, these three families were preparing to transport grain, and Luo Da Niu made a fuss, and suddenly became nervous, afraid that Qin Chuan would come around and rob them of their grain.

According to Qin Chuan's instructions, Luo Da Niu wandered back and forth in that area, and Gu Dingtian of the Hu family in the East Village killed people, he turned around and ran, and when the other party stopped chasing, he continued to make trouble.

The Zhang family and other big families also put a lot of spies in Jingle, but because Yunzhong Mountain is Zhao Sandao's territory, although that guy was pitted by Qinchuan once, there was not much left, but those big spies did not dare to enter Yunzhong Mountain, and only dared to wander on the main road around the Fen River.

Liu Youzhu and Li Dingliang's whereabouts were not able to hide from Zhao Sandao, this guy thought that the number of people who came was very small, and he wanted to come out and kill them, but soon found that this group of people was scattered and added up to hundreds of people, thinking that Qin Chuan was going to do something to him, so he hurriedly retracted his nest and prepared to defend it according to the danger, and naturally made way for Liu Youzhu and Li Dingliang.

……

Throughout the day, Qin Chuan was working out battle plans, assigning tasks and various matters.

In the evening, after a cursory dinner, he went to the artillery factory.

This is estimated to be a long time, and he has to carefully explain the matter of building guns.

Chen Zhan had already made three clay molds, a two-foot-four-inch tiger squat cannon, a five-foot Fran machine gun, and a clay mold of Napoleon's six-pounder cannon made according to Qinchuan's drawings.

Among them, small-caliber guns such as Furlong cannons and Tiger squat cannons can't use Rodman's central water cooling method, because the caliber is too small, the inner mold is also very small, and the central hole that can be reserved is very small, and it is difficult to make such a thin pipe with today's technology.

These two types of guns are mainly manufactured by the iron mold preheating method and the sealing and heat preservation method, the former controls the cooling rate of the inner wall of the barrel, so that the inside has enough time to precipitate carbonite, and the latter is used to ensure that the cooling time of the outer wall of the barrel is slower than that of the inner wall, so that the barrel forms inward stress.

The barrel made by these two technologies has higher strength, which can reduce the number of hoops on the outside of the barrel, reduce weight, and can withstand more propellants, which can correspondingly increase the range and power.

The tiger squat cannon is to be equipped, this thing is lightweight, one person can carry it, and it is like a game to shoot scattered bullets at a distance of thirty paces to hit the infantry, if it can increase the range, it will be a big killer weapon for rapid combat.

The Fran cannon is also to be equipped, although this thing is heavy, and the effective range of five feet is only about 200 paces, but it is better because of the fast rate of fire, which can form explosive and dense firepower.

And the Napoleon cannon is the main artillery that Qin Chuan wants, the weight of the six-pounder gun is only seven or eight hundred catties, but the effective firing range can reach two miles, and the twelve-pounder cannon is even more contemptuous of everything in this era.

The caliber of the six-pounder gun was about nine centimeters, and it could barely be manufactured using the central water cooling method.

Now, Chen Zhan is studying the drawings given by Qin Chuan, which were drawn by Qin Chuan with the drawings he had seen in the forum in his previous life, and Chen Zhan had to redraw them with the impressionist painting method and accurately understand the details.

Qin Chuan actually couldn't help much, so he could only put forward the general direction and requirements, such as the incubator should be made of muddy wooden boards, with good thermal insulation performance, and quickly fenced it after casting, and threw some burning coke into it to keep warm.

The sub-gun of the Franc cannon should be annealed to improve the strength of the gun tube, and the joint between the mother gun and the sub-gun must be finely polished, and a circle of sheepskin soaked in oil should be covered with the mouth of the sub-gun, so as to increase the air tightness and improve the firing range.

The barrel of the Tiger Squat Cannon should also be slightly improved, using the principle of force like the Hongyi Cannon, thickening the barrel of the chambered part, slowly thinning to the front end, reducing the number of iron hoops, and lengthening the barrel length to increase the range and power under the condition that the weight remains the same.

As for the Napoleonic six-pounder gun...... This thing is not easy to get, first of all, you have to improve the quality of cast iron, and secondly, you have to slowly explore the temperature control and strictly ensure the strength of the barrel.

It's impossible to figure it out in three or five months.

The progress of the flintlock pistol will be much faster, this thing is actually not difficult, and in another three years, Bi Maokang will be able to build it.

The focus is on spring steel, and qualified spring steel bars can ensure the ignition rate of the flintlock pistol, and the ignition rate of at least 85 percent or more is reliable.

Of course, a high ignition rate is also indispensable for high-quality flint.

The original boring machine is not a big problem, the bearings have already been made, and then the slide rails can be used to assemble a boring machine, and a batch of boring machines can be built as a standard, and then the barrel can be mass-produced.

……

After Chen Zhan and Li Xuejing pointed fingers for a long time, it was not until the second watch that Qin Chuan dragged his tired body back to the inner courtyard.

Wang Jizong hadn't slept yet, and was writing something under the oil lamp.

In the direction of the courtyard where Wang's house is located, there is occasionally a faint sound of women's laughter.

Qin Chuan looked over there and hesitated for a moment, then said to Wang Jizong's house, "Ming Zhao, come with me to see Miss Wen." ”

Wang Jizong put down the pen in his hand, walked out of the door, nodded, and walked side by side with him in the direction of Jiao Xiaosheng.

Qin Chuan said as he walked: "Ming Zhao, if I can't come back, you can help me send Miss Wen back to Fenyang, remember to ask the Wen family for three or five hundred stone grain first, Miss Wen is so handsome, five hundred stone grain is not an exaggeration, and the two sisters of the Li family, remember to collect the grain before letting them go." ”

Wang Jizong frowned slightly: "Chief steward, your life is more precious than anything else, if you really can't do it, just withdraw and return, but don't fight with Jiannu." ”

"I mean just in case."

After a few words, the courtyard where the laughter came from was reached.

Qin Chuan shouted at the room where the oil lamp was swaying: "Qin has something to say to Miss Wen, can you ask Miss Wen to come out and speak?" ”

The laughter in the room suddenly stopped, and fell silent.

After a while, Ning replied in the house: "Chief steward, in the dead of night, men and women do not kiss, please come back tomorrow." ”

Wang Jizong took over and said: "Lady, the chief steward will set out early tomorrow morning, he just wants to say goodbye to Miss Wen and say a few words." ”

The room was quiet again.

After a long time, I heard Ning Shi say: "Please wait for a while." ”

Not long after, the Ning family carried an oil lamp, and the Li sisters each took a kitchen knife and escorted Wen Suxin out.

Wen Suxin wore a pure white Luo gauze skirt, like a fairy in the faint moonlight, swayed to a place a few steps away from Qin Chuan and stopped, bowed to Qin Chuan's blessing, Ying Ying said: "The little woman wishes the chief steward a victory." ”

Qin Chuan smiled: "You don't want to know, where am I going to fight, and how long will it take?" ”

Wen Suxin replied weakly: "This is confidential military affairs, the little woman doesn't dare, and she can't ask." ”

"Hahahaha."

Qin Chuan laughed heartily a few times: "I want to go out to kill the Tartars and Jiannu, and I also want to kill a group of traitors...... It may not be back until next spring. ”

Wen Suxin's Luo gauze skirt trembled slightly, and the surprise on her soft face could be vaguely seen in the faint moonlight.

Qin Chuan said with a smile again: "During this time, you can live here with peace of mind, in Mengjiazhuang and your sister Ning for the New Year, when the spring flowers bloom in the coming year, if I haven't come back, Mingzhao will send you back to Fenyang unscathed, you should have never seen me, Mengjiazhuang is just a dream." ”

"If I can come back, I will go to Fenyang to ask your elders, if they are willing to marry you to me, I will marry you in three media and six certificates, if they are unwilling...... Then I can only overlord make a bow and cook raw rice to mature rice. ”
